A new approach to induction and imprimitivity results

Abstract

In the framework of locally compact quantum groups, we provide an induction procedure for unitary corepresentations as well as coactions on C*-algebras. We prove imprimitivity theorems that unify the existing theorems for actions and coactions of groups. We essentially use von Neumann algebraic techniques.

We added an imprimitivity characterization of induced coactions. Minor typographical corrections as well
